Steer away from the Char-broil and Master Forge Units, very low quality parts. Weber is a good choice. The Char-Broil Red's "U-emiter will only last about a year.
I have a weber E-310 and its a winner, food never taste so good.
Dont use indoors or in enclosed areas as you will suffocate.
Always use in well ventilated areas.
Dont drink and cook or you may end up in your own juices.
